When Nature Changes Everything — Red Tide, Sargassum, and the Path Not Taken

Watching the growing sargassum crisis in Tulum and along the Caribbean coast brings back memories I haven’t thought about in a long time.

People keep saying, “It’s natural.”

That’s what they said back then too.

In 2001, I was living in Mexico and pregnant for the first time at 39 years old. I was in my first trimester during a terrible red tide bloom, and the smell along the beach was overwhelming. Anyone who has experienced red tide knows the odor can be intense, but pregnancy changes everything — your senses become heightened, and even small smells can become unbearable.

The beach that once felt beautiful and healing suddenly felt heavy and sick. The air itself seemed wrong.

At the time, people brushed it off as just another natural cycle. But many locals quietly admitted it seemed to be getting worse than before.

That experience became part of the reason I returned to Canada to have my baby.

Sometimes I think about how different my life may have been if the environmental conditions had been different. One ecological event changed the direction of my life completely.

Now, years later, seeing the massive sargassum invasions covering beaches in Tulum feels strangely familiar. Once again, people say it’s natural — and yes, seaweed itself is natural. Red tide is natural too. But there is a difference between something existing in nature and something growing beyond balance.

The beaches I remember as clear, wild, and vibrant are now often buried under mountains of rotting algae. The smell, the discoloration, the marine damage — it affects not only tourism, but the emotional feeling of a place.

Nature always changes, but lately it feels like humanity is pushing many natural systems past their limits.

Maybe that’s why these stories matter.

Environmental changes are never just about science or tourism statistics. They quietly alter human lives, relationships, health, migration, memories, and the paths people take.

Sometimes a tide changes more than a shoreline.
